Nanoracks made it first demonstration of metal cutting in space. TechCrunch he says:
The experiment was carried out in May by Nanoracks and its parent company Voyager Space, when it was in orbit with the launch of SpaceX Transporter 5.
But the company published recently the details (on Friday) of the project. Her goal Missions Outpost Mars Demo-1 was to cut a piece of corrosion-resistant metal similar to the outer shell of United Launch Alliance's Vulcan Centaur, something common in space debris.
The cutting was done using a technique called friction milling. Welding and metal cutting is one mode on Earth that causes dust and debris, which just fall to the ground.
But when it's done "in space, in a vacuum, that doesn't happen," Marshall Smith, senior vice president of space systems at Nanoracks, told TechCrunch in May. "What we want to do is limit the debris, not necessarily because it might be a matter of micrometeorites, but mainly because we want to keep our work environment clean."
The whole project took about a minute. The main objective – cutting a small sample of steel – was successfully completed. It was conducted in collaboration with Maxar Technologies, which developed the robotic arm that performed the cutting. This arm used a commercially available friction milling effector and the entire structure was installed on the Outpost spacecraft to ensure no debris would escape.
Indeed, one of the main aims of the demonstration was to produce no garbage – and it worked.
Nanoracks cut a type of very durable metal used in a rocket's upper stage because the company's long-term goal is to modify these used upper stages and turn them into orbital platforms.
According to Smith, this is just the beginning. In the future, Nanoracks will attempt larger-scale cuts in its quest to eventually realize larger structures.
